Abstract (en)

[origin: WO2009119228A1] In a torque control device for an internal combustion engine (1), a driving-system torque calculation unit calculates a driving-system torque operating on a driving system (5), based on a requested torque at a time of acceleration. A torque control unit (20) executes torque control so that a gradient of the driving-system torque becomes equal to or smaller than a predetermined value, based on the driving-system torque calculated by the driving-system torque calculation unit. Thereby, since an amount of twist of the driving system can be maintained equal to or smaller than a predetermined value, repetitive shock can be suppressed, and acceleration shock can be effectively suppressed, too. Response deterioration and fuel consumption deterioration at the time of acceleration can be prevented.
